I rid my tanks of most of algae by cutting my lights on hours from 16
to 14.

Good suggestion. I think I'm going to buy a timer and do the same thing. I'm
not even sure how long they're on each day. I shut them off at different
times of the night, turn them on different times in the morning etc. A
cheap timer from Wally World should do the trick.
